Comment Notify

Looking for a plugin that when a user comments, and I reply they will recieve an email telling them tat I replied to there comment. I’ve tried a few so far and they didn’t work, I had one long time ago but I don’t remember what it was called. it actually had a tab under the dashboard / comment tab.

Also, wouldn’t mind a plugin to have other users comment and have emails sent to other users just not admins. or mods
